They differ in a similar way to how React differs from SolidJS.
In react when state changes the component functions that depended on that state are rerun to compute what the component should now look like. Then react diffs the new output with the previous to touch only the parts that changed in the DOM.
In solidjs the component function runs only once (when the component is instantiated), when state changes signals will trigger and cause the specific parts of the DOM that depended on them to change. This is generally more efficient.
